Leners Parme No. 99,047, dem January 25, 1870.

The Schedule referred to in thais Letten Patent and making par: of thesama clare the following to be afull, clear, and exact descriptionthereof, reference being had to the accompanying drawings, making a partof this specification, in which- Figure` 1, of Sheet No. 1,' is a frontview of the apparatus embodying my invent-ion.

Figure .2, ot'Sbeet No. 2, is a plan of the upper v'portion of theapparatus, iepresentiugthe printing- `anangement on a circularplatform.- 'A jFgllleg` 9nd platformdilaced'helupythatshowu inflig. 2.

Figure'4, of Sheet No. 3, is a horizontal section o'u the line a: z,igvl.

The object of my invention is to transmit come munication, in printedform, over telegiaph-wires, and

without the use ot an attendant, by means ofan aur 'roulatie-workingapparatus, thus enabling brokers, merchants,'or headsfot' departments,otc., to correspond directly and privately with their agents in distantparts:v i v Andmy inventionconsists in the employment of a type-Wheel,bearing on its face as many letters, figures, and signs as'there are onthe keys of Ithe keyaround which the'paper to` be printed 'is guided andheld by fingers or` frame, said impression-roller being -thrown againstthe type-wheel by means of levers and cams on lam-wheel; the latter tobe rotated by a train. of wheels, drum, and weight, .and stopped orreleased by means` of escapement-wheels, escapement, and

'second magnet. .'lhe second magnet is'connected by .conducting-wirewith the. base of key-board, while the v magnet operating on thrCtype-wheel is in electriccoinmunlcation, by means o1 a conducting-wire,with the break-spring, or drum. f' Referring to the. dxawings- A is a.base-plate, ou* which a key-board, B, is arranged, containing forty`one' keys, marked as explained below, to economiz'e space; and to makeit also con- `venient for the opelator, a' number of the keys is placedupon and between every two of the larger and forward keys, like a. pianokey-board.

`The keys move 'on pivots, and, with their narrow and tapering ends',projecito the rear, toward a large metallic drum, O, which being placedvparallel to the keys, is provided with projecting pins, a a a,correspending in numberv toi the keys. `Atene .6nd, and around itscircumferenogare inserted breaks, of nouconducting material, b

b, forty-one in number, and

a break-spring, c, placed in such a position as to bein contact with thedrum 0, andpresscd against thc latter by means of' a. spring, to whichthe conductingwire mis attached, transmitting the electric current tothe drum, when it touches the space between two breaks, Il b, and breaksthe 'current when coming in contact with one of the insulator-breaks b.

The drnmG. is set in motion by a weight or spring acting upon ,a drum,c, aud a train of wheels, fg h i, the ratchet-wheel k, on drum c, andcatch It', being attached to wheel f, for thel purpose 'of allowing the4drum C to move in one directiononly.

The fiier 'l is attached, for regulating the motion.

' The drum O is tted loosely ou its shaft, und rotates with the same4b'y--means of friction-break d, in such annahm-.r (hat bjn themotion-of the drum C is stopped by one of their projecting -pins coming.in contact with a raised key, the shaft moves on, but as soon as drum Gbewiuosreleased, the friction of break d causes the drum to move 'withthe shaft.

"lbe standards 1, 2,1tnd 3, supportaplatform", D, on which are placedtwo setsof magnets, E and F, with the cscapcmcuts G. and H,Vand'escapemei1t-wheels G' and H. The escapementwheel- H. is connectedoperated by weight or spring. Ahoveplatform D isl placed anotherplatform, K,

'and supported in a suitable manner, on which the board, and anescapement, armature, and magnet, by :which the typewheel is rotated,and impression-roller,

.tions or teeth, is fittedoutbe shaft s, which, passing through platformK, supports, at its upper portion, the type-wheel L. 'lhe type-wheel isprovided ou the facewith the same letters, ligures, and signs as there.are ou the keys, and pinsou the drum, and arranged in a suitable order,it receives theink from the inkingrollers t.

The escapement-wheel H is fitted on shaft u, which has attached to itsupper portiou'tlie wheel N, having as many cams as there areindentations onwheel H,

' the number of them heilig immaterial.

The cains of wheelN operate on end of lever P, on the lopposite end ofwhich is attached a roller, It, around which'thepa1`1er to be printed onis passed, and the forked-shapedfingers S, forholding the paper against.roller R. 'lhe latter receives, also, a rotary motion, by means ot'spring Tacting against aratchet underneath and forming a part of rollerR, the spring T being brought in action by the backward motion' ofroller 1t.

The motion of'eam-wheel N throws the roller R, with the paper, againstvthe type-wheelL, while the spring `'l frees the rollerl 1t' fromtype-wheel L, and gives the former a rotarylmotion, thus pushing thepaper along, and spring `T returns the lever P, through its pressure onfingers Slnto proper position to be acted upon by the following cams.

In the rear ofbaselate A are placed three binding-screws, V V V". isfor' receiving the wire for type-wheel circuit, whlleVls for that of theimpressioncircuit. After passing the biudiug-screws V V', the wires maybe united in one line, which passes o to a. distant apparatus, or intothe ground. Thev bindingscrew V" receives the current from the battery,and carries it, by line r, to the standard of drum C.

For operating this apparatus, linger the keys representing therespective letters, figures, and signs. This will stop the drum O at acorresponding pin, a, the break-spring c resting on one of thekinsulated breaks b. 'lhe acting-key will touch the hase of keyboard, andthus an electric current becomes established, passing from battery,through binding-screw V", and wire r, `to the drum O, andfrom there,through pinva, to the opposite hey and base 0r" key-board, and throughwire n to magnet F; from there, through the impression-current to thebinding-screw V', and through the united line into the ground. Butduring the electric action, the magnet-s F will attract the oppositearmature ot' escapemcnt H, and set free the escapementwheel H', to bemoved bythe train of wheels, weight, or spring, and by means of shaft u,causes the eamwheel N to follow the motion, and act upon the lever I),throwing roller It, with the paper, against the typewheel, forreceiving,r theimpression. Now, by releasing the key, this circuitbecomes broken, the drum O commencing to revolve until stopped again,the breakspring c passing over thehinsulated breaks b l, an'd theintervening spaces, and opens and closes the circuit, which passes, bymeans of wire mi, magnet E, and binding-screw V, to the united line, andto the ground, and

o', to drum O g but` as uiten astiiis circuit is changed,"

as often the magnets will operate the escapement (l,

escapement-wheel G', and with it the type-wheel L. In practice, itisunderstood that the key-board,

drum, and all parts shown iu fig. 4, are in the hands of' the partysending the message, while all the parts on the two platforms, as Shownin figs. 2 and 3, are under the observation of the receiving-party; orthere may be two apparatus, one on each end of the uni ted line.

In arranging the letters, figures, and signs, I iind the followingmethod as most practical and time-savin g Commencing at the right'ofkey-board, and calling the first key dot;tl\e next above, blank; thethird below, 1, and so 011,3, 7, 5, 8, 4, 2, 6, 9, 0; blank G, B, I,'11. O, Il, C, Q, K, Il, A, 8:, V, I),

ters, figures, and signs, are arranged in the same crdcr on thetype-wheel.

Having fully described myiuvention,

Whatl claim as new, and desire to secure by Letters 1atelitis- 1. rIhecombination of key-board B, drum O, insulator-breaks b, break-Spring c,train of wheels, with magnet E, cscapeniontG, wheel G', and type-wheelL, in the manner and for the purpose Substantially as described.

2. rlhc combination of type-wheel L with'roller'lt, lever P, cam-wheelN, esca-pement H and wheel H', and magnet I", in the manner and for thcpurpose as stated.

3. The combination of key-board B, drum C, insui later-breaks b,break-spring c, magnet E, cscapement (lr, type-wheel L, with roller It,lever I, cam-wl-ieel N, escapement H, and magnet F, when arranged :inthe manner :nul for the purpose as set forth.
